We have a new 12 user network that uses IMAP for email on their PC's and mobile devices. Most of the mobile devices are iOs7 iphone 5's or MS Pro tablets. The PC's are Windows 7 & 8. There is one lonely MAC user.
Outlook 2010 and Thunderbird were used to migrate individual accounts from a previous hosts windows server to our linux web server on site5. Both servers are still live but the old server incoming uses an ip address instead of mail. I'm wondering if there is a possible conflict here?
On a per user basis, I setup old and new email accounts and moved the IMAP emails from old to new folders by the 'move' process. (see outlook folders img) On each users email client (outlook 2010 - 2013) a new IMAP account pointing to the new linux server was setup. Some folders populated normally others did not.
Oddly a 3rd data file was created locally if the old IMAP data file was present. This couldn't be deleted as it was linked to the email.
So what I have now is a variety of issues. I have emails disappearing, emails not arriving that were before, folders not showing up. There seems to be discrepancies in emails and folders between iphone and outlook. Gaps in historical email dates on iphones. (although these seem to be narrowing)
I've looked this for 3 days and have a head full of information but need direction! Your assistance is appreciated!
